Management Comment
This patent is one of the patents involved in Wi-LAN’s EDTX case Case 2:07-cv-00473.  It has now become very common for Defendants in patent infringement lawsuits to, as part of their defense strategy, file requests for re-examination of patents at issue in such actions.  It is expected that the U.S. Patent and Trademark Office will respond to this request within the next 3 months.
